IMPROVEMENT IN WATER-GLQSEI v"V.A.'I'.|VES.

The Schedule referred to in these Letters Patent and making part 0f the Same- Be it known that I, HERMAN STRATER, Jr., of Boston, in the count-y of Suiiolk and State of Massachusetts, have invented an Improved later-Closet Valve; and I do hereby declare that the following, taken in connection with the drawings wliichraccompany and fo'rm part of this speciiication, is a descripftion of my invention sufficient to enable those skilled in the art to practice it.

My invention relates to lthe construction of water? closet valves of that class in which the valve is so` arranged as to be prevented from sudden closing, the water continuing to low past the valve after the pan is raised by the weighted lever, lso as to lill the/pan sufficiently to flush or seal the bottom oiT the hopper with water. y

My improvement has particular reference to the arrangement of theJ inlet-pipe and its induction-orifices,

' and to the arrangement andconstructon of the slowy closing valve.

cup or chamber, e, from one side of which (near the lbottotn) leads a tine orifice, f, covered by a strainer, g.

1n this chamber or cylinder is a stationary piston, 71 at. the end of' a stein, fi, projecting down from a diaphragm, j, extending across the bottom of the inlettube, or from the cap k, and the cylinder e plays vertically upon this piston. A

At the top oi' the cock is a cap, k, which is made as a flanged ring, the Vring screwing down upon the top of the body a, and its flange Z, projecting inwardly, over the' edge'ofa round washer-plate, m, (which is a continuation ot' the diaphragm plate j,`) a leather or other suitable packingring, o, being interposed be-V tween the washer-plate m and the top edge ofthe body a, to pack the joints between the cap and the body, and

. between the inlet-pipe and the cap.

opening into .such chamber n, and out through the pipe a: into the water-closet hopper, to cleanse the closet. j

\Vhen the weighted lever' that operatesthe pan is raised, it raises with it the valve-stem d, and lii'ts the valve c from its seat.

The inlet-pipe s opens directly int-o the main chamber a, and keeps the chamber iilled, and, when the valve is opened, water rushes from the main chamber into the auxiliary chamber, and thence into the' bowl or hopper of the water-closet.

The cylinder is-also filled with water (beneath the plunger) when the valve isfclosed, and, as the valve rises, the upward movement ot' the cylinder causes this water to be pressed out' through the orifice f and the gauze g.

Vhen the pan-operatiug lever is allowed to fall, it`

drops from the valve-stem, and the valve, instead ot immediat-elyclosing, only falls down to its seat as'hst as water from the main chamber can percolate throng-h the gauze and aperture into the cylinder beneatlrthe plunger, thus keeping the'valve open after the 'pan has risen, and allowing water to llow into and lrise in the pan until the valve reaches its sea-t and shuts oii further flow of water from the main into the auxiliary chamber, at which time the water in the pan will have sealed the bottom-of the hopper or container.

The valve is moved -down by gravity andby the friction and downward pressure of the current of water. To increase the pressure-surface, I make, upon the outer` surface of the valve-cylinder, a series ot' shoulders or projections, p, furnishing surfaces against which the pressure of the Water acts to hasten or facilitate the descent ofthe valve.

When the head of water is not great, a spring, q, may also be used, the stress of such spring tending to force the valve down, as will be readily understood.

In slow-closing valves, as heretofore made, the outlet-pipe and inlet-pipe have both led directly from the main body orvalve-containing case, and have been l rela-tively fixed upon opposite endsot' the said case, whereas it is often desirable to have the inlet and outlet-pipes not in the same plane, but capable ct' relative angular adjustment. t

It is also desirablel to have the water enter so as to press or flow equally upon all sides of the valve or case, and its valve and suitable inlet and 'outlet-pipes, Also, in combination with the reciprocating valve n the reciprocatingr cap or cylinder, (over tl1evalve,) and c and cylinder e, the spring g, substantially as de.-

tlie stationary piston, constructed and arranged to opscribed.
